A former British intelligence officer involved in analysing evidence about Iraqi weapons programmes has accused senior officials of ignoring his advice to amend a pre-war document about Iraq.
The document, which was used by Prime Minister Tony Blair to justify the invasion of Iraq, accused Saddam Hussein of being ready to use weapons of mass destruction.
Brian Jones, who was head of intelligence staff at the Ministry of Defence, said his team could not confirm that Iraq had stockpiles of chemical and biological weapons.
Meanwhile, it is expected Mr Blair's most senior intelligence officer and his closest aides are likely to bear the brunt of criticism in a report on intelligence failings in Britain's case for invading Iraq.
A report on the matter will be released on Wednesday.
Last week, a US Senate committee report said American spy agencies overstated the threat of Iraqi weapons, relied on dubious sources and ignored contrary evidence before the war.
